In yesterday report, collecting cranberries, uh, sweet berries, by the help of fox is classified into the group of automatic farm.
So I read through the written rules in forums, and found rules related to automatic farm is only under section regarding to redstone.
There is also doubt about how different they are between collecting eggs from chicken, and collecting berries with help of fox, which both methods using hopper. As of now, I have never heard of people being required to stop collecting egg via hopper, unless what I know is outdated.
Also I hope that you do not mind me for not creating another post or using bot to make this suggestion: Replace the word ‘pigmen’ in the rules with ‘zombified piglins’.
Thanks.
